Discrete Choice Modeling in Education: An Innovative Method to Assess Teaching Practices     

Vasilis Grammatikopoulos  Athanasios Gregoriadis  Michalis Linardakis 《Educational Measurement》2019,38(3):46-54

Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.  相似文献

长江口深水航道船舶超宽交会通航效率分析     

周伟  肖英杰  郑剑 《上海海事大学学报》2019,40(2):1-5

为提高长江口深水航道通过能力,减少由船舶交会宽度限制产生的延误,通过分析船舶超宽交会现状,建立仿真逻辑模型,运用Arena进行离散仿真试验。采集长江口深水航道交通流数据,设置不同的船舶交会宽度限制,对大型船舶进出港过程进行仿真,分析不同交会宽度限制对船舶通航的影响,获得被延误船舶比例、被延误船舶数量和延误时间,进而提出提升通过能力的建议。试验表明,采用Arena进行离散仿真能够量化分析超宽交会对通航效率的影响,可为航道拓宽和交通管理提供科学依据。  相似文献   

Gender-preferential intergenerational patterns in primary educational attainment: An econometric approach to a case in rural Mindanao,the Philippines     

《International Journal of Educational Development》2016

This study investigates the factors determining children's educational attainment, focusing on gender-differential intergenerational patterns, by employing a case study from rural Mindanao. The result mainly shows, unlike general trends in developing countries, educational attainment is more favorable for girls; maternal education level is equally associated with daughters’ and sons’ education levels, and paternal education level is preferentially favorable to their sons. To reduce the disparity, suggestions include providing boy-specific interventions to enhance the magnitude of the father–son educational virtuous circle and comparing the magnitude of gender-equal maternal and boy-preferential paternal education influences to specify which effect is larger.  相似文献

随机变量的熵与标准熵     

王雪琴 《三门峡职业技术学院学报》2003,2(4):33-34

本文研究随机变量的熵与标准熵、标准差之间的关系,得出的结论是:对于离散型的随机变量熵与标准熵相等,与标准差无关;对于连续型随机变量ξ(ξ是的ξ标准化随机变量),熵H(ξ)等于它的标准熵H(ξ)加标准差的对数σ。从而揭示出两类常见的随机变量之间的本质性差异:离散型随机变量的不确定度与离散度无关,连续型随机变量的不确定度与离散度(标准差)呈对数关系。  相似文献
